Feature request: Force 24-bit Z-buffer #150

Closed ZellSF closed 8 months ago

Now that DDrawCompat has support for forcing higher resolutions some old games look bad at times at those resolutions because of z-fighting. I've tested "Arcturus: The Curse and Loss of Divinity" and "Nelson Piquet's Grand Prix Evolution" in DDrawCompat with forced resolution and they look worse than dgVoodoo/Peixoto with forced 24-bit Z-buffer.

"Hydro Thunder", "Simon The Sorcerer 3D" and "Star Wars Episode 1 Racer" are three other titles I know need 24-bit Z-buffer to look optimal, though I haven't checked if those work in DDrawCompat.

Quick search tells me "Rayman 2" and "Vampire: the Masquerade - Redemption" also would benefit from such a setting. Not that I know if it's viable to implement in DDrawCompat.

I'm pretty sure I've run into other games with this problem too, I just don't remember them at the moment (I do remember two more, but they're Direct3D8).

It should be possible. I'll try to add an option for it in the next release.
